A2SD, partitioning and Nand Switching (internal to external) for Optimus 3D

Please someone more experienced than me check the prosedure!!! Till I remove this line go with extreme caution
I have an enormous amount of applications inherited from the partition-able optimus 2x. I got optimus 3D as an upgrade but I couldn’t intall not even half of them. So I was trying to find ways to repartition /data as I had done with optimus 2x but with no success.
Then I got an idea... why not A2SD style? So it begins
Disclaimer: Have in mind that I’ve done nasty stuff which could brick the phone badly. I take no responsibility for breaking your phone even if you follow my guide perfectly. I am no developer and I can make mistakes so please don’t continue if you don’t understand what I am telling you to do. Also be careful since I dont know how future lg updates will react
My composition is: Thiaiz Rom V0.1, clockworkmod touch, rooted ofc and I have installed most drivers found on this forum for o3d.
Before you begin get a backup of your internal memory, sd card, titanium backup and nand backup to a pc. You WILL loose internal memory data. The rest just to be safe....
Drawbacks: Your internal memory will be around 2-3gbs smaller and wont be able to be mounted to the pc. You could brick your phone.
While all these can be done with a cwm zip script I did it manually. Also since my phone works fine know and my time is short I dont really want to go to the reformating coping restoring backups again. This means that while I write this guide I dont actually run these command only checking them if they are correct.
Lets start.
First shutdown your phone. Open it to recovery by pressing down button and power for 7-8 seconds. Release when you see LG logo. While in recovery connect your device with the pc with a usb cable. Open command prompt on your windows pc and do a
adb shell
Now you are probably ready to send commands. If not use a guide like this http://www.addictivetips.com/mobile/what-is-adb-and-how-to-install-it-android/
at the shell do a
Code:
# cd /dev/block
#ls
you will see all your partitions. mmcblk0 is the internal memory and mmcblk1 is the sd card.
Code:
# parted mmcblk0
(parted) print
now you see the partitions
You should see something like this
Code:
Number Start End Size File system Name Flags
1 131kB 262kB 131kB x-loader
2 262kB 393kB 131kB nv1
3 393kB 524kB 131kB nv2
4 524kB 1049kB 524kB u-boot
5 1049kB 11.5MB 10.5MB kernel
6 11.5MB 22.0MB 10.5MB recovery
7 22.0MB 651MB 629MB ext3 system
8 651MB 1725MB 1074MB ext3 userdata
9 1725MB 1859MB 134MB fsswap
10 1859MB 1926MB 67.1MB ext3 cache
11 1926MB 1928MB 2097kB ext3 lgdrm
12 1928MB 1929MB 1049kB divxkey
13 1929MB 1950MB 21.0MB fota
14 1950MB 1955MB 4194kB ext3 misc
15 1955MB 7944MB 5989MB fat32 msftres
we are going to work on partition 15 starting by deleting it. Be very carefull here what you delete
Code:
(parted) rm 15
now we want to create 2 more partitions. The 1955-4944 and 4944-7944 will give you around 3gb for apps and 3gb for internal memory. Tweak it at your needs but always follow the numbers. I meant if your print gave you this output
Code:
15 1955MB 7945MB 2989MB fat32
use 7945 and not 7944
Code:
(parted) mkpartfs primary fat32 1955 4944
(parted) mkpartfs primary ext2 4944 7944
now the command print should give you two more partitions
Code:
15 1955MB 4944MB 2989MB fat32 msftres
16 4944MB 7944MB 3000MB ext2
quit parted to update the ext2 to ext3
Code:
(parted) quit
#mke2fs /dev/block/mmcblk0p16
#tune2fs -j /dev/block/mmcblk0p16
Now our phone is ready for A2SD. Reboot the phone.
After finish rebooting continue via adb or terminal (I used terminal because I was in a 3 hours trip with bus ) and es file explorer with root and rw options on
we need to tweak /etc/vold.fstab to change the mount points. You can change it with es file explorer
My file is:
Code:
dev_mount sdcard /mnt/sdcard auto /devices/platform/mmci-omap-hs.0/mmc_host/mmc1
dev_mount extsdcard /mnt/sdcard/_ExternalSD 15 /devices/platform/mmci-omap-hs.1/mmc_host/mmc0
then we need to create the mount point for our new partition. I did it at /mnt/a2sd but you can do it anyware including the standard /system/sd
Code:
#mkdir /mnt/a2sd
#mkdir /mnt/emmc
now we need to mout our new partition everytime the system starts. I opened /etc/init.d/thiaizSDbooster and added few lines
Code:
mkdir /mnt/a2sd
mount -w /dev/block/mmcblk0p16 /mnt/a2sd
mkdir /mnt/emmc
mount -w /dev/block/mmcblk0p15 /mnt/emmc
ln -s /mnt/a2sd/data/app /data/app
ln -s /mnt/a2sd/data/data /data/data
dont forget to make the correct permitions again after the edit
now you need to mount the new partition to your mount point
Code:
#mount -w /dev/block/mmcblk0p16 /mnt/a2sd
and copy the data files you will link there
Code:
#cp -a /data /mnt/a2sd
now careful youll delete the /data/app and /data/data from /data
Code:
#rm -r /data/app
#rm -r /data/data
and create the links
Code:
#ln -s /mnt/a2sd/data/app /data/app
#ln -s /mnt/a2sd/data/data /data/data
Reboot the phone and you are ready to go!
To mount the sd card to the pc you will need an app from market https://market.android.com/details?id=com.rafoid.multimountsdcard.widget.free

want to give it a try but I need to know if there is a way to revert back if anything goes wrong. Will a restore of a previous backup return things to normal?or flashing a kdz? thanx anyway.any try to improve our phones is worth praize...

Make a nand back-up in another sd card, if you re lucky and can still boot upto recovery then you can restore or you can boot to download mode. Last resort will be to flash a bin or kdz file then restore your nand back up.
I bricked my phone 5 times in one month 2 times in 1 day. I still figured how to restore, just relax and think before you do crazy stuff, all the answers are in XDA.

@orlox tested it and gives me phone memory damage, forgot to pull the logs and do some ss, well anyways I won't be doing this one, I was setting up for the s2e and link2sd stuff -- that one is not that risky.

The "damage part" is because you probably didnt change the vold file. Its not something to worry. After you tell vold what partition to mount (15) it will be ok

not yet, got other stuff in hand... i'll try to report tom* its already 2am here and have work at 4am -- cooked.

I made a mistake somewhere and am stuck. Can't sleep now, I'll have to figure this thing thorough.
---------- Post added at 07:20 AM ---------- Previous post was at 07:12 AM ----------
btw you can try this --> install link2sd let it install the script needed to mount 2nd sd part, then edit it (init.d folder)
--> add this before mounting sdext2
sleep 2
mkdir /sd-ext
sleep 2
--> then after mounting sdext2 insert this
sleep 2
mount -o bind /data/sdext2 /sd-ext
-----------------------------------------
install s2e
move dl cache (dont move any apps, let link2sd do that)
reboot.
----------------------------------------------
works with thiaz boot image only
the risk is low and would not probably brick your phone but try it at your own risk (disclaimer) --> this is generic, do your mods.
any problems will discuss after I unbrick my phone lol.

Generic scripts are not working well. I was trying with dark tremors first. I think manual is safer. Also Someone may want to partition sd instead of nand. Its safer but I think its a waste of space.
The good thing is that parted works so we don't need a tool like nvflash. Also /data had a limit at 2GB I think. With a2sd there is no limit.

Boot loop Unresolvable? Hardware problem?

Hey all, new to xda. Hope I'm not asking stupid questions.
My friend gave me a Galaxy S to fix. Model: GT-I9003.
It has a boot loop problem, cycling the Samsung introduction animation (and sound first time round). The recovery mode didn't work to start with - also trapped in a boot loop.
I followed the instructions here (using Odin3 v1.85) and flashed XXKPE. It seemed to all work fine, but the boot loop remained. I booted it into recovery mode and the following error messages appear.
E:failed to mount /data (No such file or directory)
Click to expand...
Click to collapse
and under -- Wiping data...
E:format_volume: rfs format failed on /dev/block/mmcblk0p3
Click to expand...
Click to collapse
then
Data wipe failed.
Click to expand...

From my research I believe it's a corrupted internal SD-Card and is fixed via parted? Could anyone go into more detail on how I would do this?
Many thanks.

I am facing a similar problem on my Galaxy SL... Need a solution too... I would appreciate any help...

Data partition has been corrupted, try flashing userdata.rfs with heimdall. A friend of mine had an stock/untouched phone and this happened to it, even with the corrupted partition i was able to boot cyanogenmod, and tried a lot of things, but nothing worked, it was on warranty, so i flashed back the original firmware and he took it to the service center.

If you want to try do this:
Flash bam kernel PDA_BCK_CF-root_universal_beta14fix.tar (http://forum.xda-developers.com/showthread.php?t=1355675)
Then from CWM flash cyanogenmod (i used cm7, but you can try with cm9)
after that the phone should boot into cyanogemod and give an error on the notification bar
extract the 6 files off the zip i attached and copy them to /xbin
from terminal emulator or adb shell run this for the 6 files:
Code:
chmod 0755 <file>
then run:
Code:
parted /dev/block/mmcblk0 mkfs ext2
When it asks for the partition number, enter 3
finally reboot, and if it worked you can flash a stock rom again, thats it, good luck

My phone boots up, but there are random reboots. Tried a lot of stock and custom ROMs... Nothing works... Warranty expired last week...

Thanks for your time. I appreciate it.

Sorry, I'm very new at this - my first hour doing this kind of thing. Could you explain the procedure in more detail - I would like to learn (make the best of a bad situation).
Am I right to say that the Bam Custom Kernel gives super-root level privileges? Allowing the CWM to fiddle with partions?
I've downloaded the normalboot.img for BCK. How do I flash this to my device? Could you link me to a tutorial?
EDIT: Alternatively could you point me to all the prerequisites I need to properly understand the problem and the methods required to fix it?

I tried that... My phone was booting up...
I have Android SDK on my PC... It includes some tools like ADB.
If your phone is rooted, you can use ADB to do things, like formatting...
Connected my phone. Booted into recovery. From Command Prompt, I went to ADB folder, then typed "adb shell". Then, typed in the parted command, and followed steps. Successfully done...
But the problem continues...
I have found many other users have faced this problem -- http://forum.xda-developers.com/showthread.php?t=1736118
I am disappointed. My phone is no longer in warranty... I am too late...

it is possible that using cyanogenmod and S2E (simple2ext) will work as a workaround until you send it to service center.
grab a copy of s2e and push it to /system/app/
Repartition your External-SD using the same method used for phones with low storage capacity, warning: it will erase all the data in it, so make backups
Start s2e and mark to move:
App and Private app
Applications data
Dalvik and download cache
This makes another partition, and it does not fix data, but at least you should be able to install apps.

I face this problem too. Please someone give us the solution.

Update: I flashed BAM Custom Kernel and put it in recovery mode. Attached it to the computer, but I'm stuck at this error message.
Thanks again.

More information
EDIT: There doesn't seem to be a /data partition at all! I feel I'm getting closer to fixing this.

There are 2 storages chips on this phone, one is mmc and the other is onenand.
I think the mmc chip is dead... it contains both /data and internal-SD, the onenand still works, it contains (system cache and dbdata), you can still use the phone with cyanogenmod if you mount everything that should go on /data on a partition in the external-SD, (the method i described with s2e). However there are some drawbacks, the SD needs to be class 6 or above to maintain the system speed, and the life of the sd is going to be reduced because of the more intensive use.

Thanks. Is there a way to replace the mmc chip without sending it to Samsung?
I've flashed XXFPE then Bam Custom Kernel then when I try install cm7 from CWM it gives:
Checking state of RFS/EXT4...
assert failed: run_program("/tmp/updater.sh") == 0
E: Error in /emmc/update-cm-7.1.0-GalaxySL-Kang-singed.zip

Trying with MIUI instead.
EDIT: MIUI does this too.
How do I get around this? Can't I flash cm7 via Odin like the stock roms?

I think that the problem is when /tmp/updater.sh tries to mount /emmc your internal memory (EDIT: I've just noticed you tried with CM7, so, if I remember correctly, /emmc is the external memory, but I think that the problem is always the impossibility to mount the internal memory.) to backup your /efs directory. Because of the not avaible internal memory (/emmc) it simply exits and aborts the installation.
A simple change in updater.sh will allow you to install CyanogenMod, but wait for a confirmation from alfrix, maybe there's something more.
Anyway here there's a thread of a user with the same problem, he solved this by using the external SD as internal SD, as alfrix suggested.

strange, before touching anything try with the release i used that time (14.12.2011), if it doesn't work, then edit the updater.sh and remove
Code:
if ! /tmp/busybox mount -t ext4 /dev/block/mmcblk0p3 /data ; then
/tmp/busybox umount /data
/tmp/make_ext4fs -b 4096 -g 32768 -i 8192 -I 256 -a /data /dev/block/mmcblk0p3
fi
EDIT: is there any mmcblk on /dev/block?
Code:
ls /dev/block/

Weird the has mmcblk0 reappeared.
Code:
~ # ls /dev/block
ls /dev/block
bml0!c bml6 loop6 ram13 ram9 stl6 tfsr2

Can't mount storage on sony xperia L. Hard brick Xperia L during repartition.

here is what i did in my sony xperia L and now i anything that can help kindly let me know
I rooted my device and then i officially unlocked my bootloader but after unlocking bootloader the phone was stuck in bootlooop so i installed stock recovery in the phone using flashtool and phone was just fine then. I did all this in order to change the partition of my phone.
Now i installed cwm recovery and after that phone i did the following commands
Open a command window: CMD, then get into shell:
adb shell
Once in shell, type:
umount /storage
parted /dev/block/mmcblk0
print
This prints out the partition information of your phone's memory chip
You will see the partition numbers in the first column, partition names in the last one,
in between you have the start/end memory index and the partition size
------start---end---size
...
31---1795---3506---1711---userdata
32---3506---7818---4312---sdcard
In the above output, consider the values indicated in italic as not to be changed !
Now calculate (open a spreadsheed if you like) the new value for the end of the userdata partition,
and use the same value for the start of the sdcard partition
On your sheet it should look something like this if you added 2048 to the userdata size
------start---end---size
31---1795---5554---3759---userdata
32---5554---7818---2264---sdcard
Remove userdata and sdcard partitions:
rm 31
rm 32
Create the new userdata and sdcard partitions:
mkpartfs logical ext2 1795 5554
name 31 userdata
mkpartfs logical fat32 5554 7818
name 32 sdcard
Exit parted to go to the adb shell again:
quit
userdata partition (31) needs to have ext4 file system
The following will do the ext2->ext4 conversion:
cd /storage/sdcard1/fs-utils
tune2fs -j /dev/block/mmcblk0p31
tune2fs -O extents,uninit_bg,dir_index /dev/block/mmcblk0p31
e2fsck -fpDC0 /dev/block/mmcblk0p31
Now when i restart my phone or even open the phone in cwm recovery it says cannot mount storage.
I tried installing the Rom again using flashtool it does not work and device gets disconnected probably coz now i am not able to mount my storage.
I tried to start adb shell and revert the changes i made in the above command in order to bring phone back to normal but now adb says no device is found.
I went to the customer service centre of sony they said they will change the motherboard.
Now my question is there any way i can fix my phone kindly tell me. I will really appreciate it Since i am not a software developer so i do not know any commands. Is there any way i can change my storage settings so they can be mounted again kindly let me know.

Just a question here, why did you want to change the partition of your phone?_? And no there isnt a way to revert thats a hard brick

Changing the motherboard will be the quickest method for Sony, which will not cause any trouble for them. You could ask the price for doing a low level format and restoring the partitions etc. Though I don't if they can do this in this case.

Nexus 5 32GB shows only 12.55GB. Cannot Use Stock Recovery, gets stuck on formating.

I'm having the issue of missing storage with a 32GB phone.
Trying the instructions here - https://forum.xda-developers.com/showpost.php?p=47156078&postcount=2
The issue is the stock recovery doesn't seem to work for me. When you go to recovery mode with it flashed it gets stuck on the android symbol standing up with the spinning gear. I've left this overnight for over 10 hours.
I can resolve this if I flash TWRP recovery which then enables the phone to boot into android setup properly but it then reverts back to the issue of missing storage.

32 become 16 GB, the last last last attempt to solve the issue

I was in the same situation, metod 1, metod 2 any method to fix it did not work
I've solved it by doing this (make this at your own risk, FIRST be sure that your emmc is not damaged):
root your device, and put parted binary ( find it in the forum) in system/bin with execution permission.
Then reboot in twrp recovery, then in twrp recovery terminal or in adb root shell, type this :
Code:
Code:
mount system
umount /dev/block/mmcblk0p28
parted /dev/block/mmcblk0
check 28
it should say something like
Code:
Code:
Error: The backup GPT table is not at the end of the disk, as it should be.
This might mean that another operating system believes the disk is smaller.
Fix, by moving the backup to the end (and removing the old backup)?
Fix/Ignore/Cancel? Fix
Warning: Not all of the space available to /dev/block/mmcblk0 appears to be
used, you can fix the GPT to use all of the space (an extra xxxxxx blocks) or
continue with the current setting?

now type:

Code:

the last two partitions should be:
Code:
28 2032MB 15.8GB 13.7GB userdata
29 15.8GB 15.8GB 5632B grow
if EVERYTHING is like that, let's make a try, type:
Code:
Code:
mkpart primary ext4 15.8GB 25.8GB name 30 trypart
name 30 trypart
print
if you can make trypart without errors and you can see trypart with the print command then
you can proceed to the next step, that will ERASE your data ( worse your userdata partition, before recreating it), type:
Code:
Code:
rm 30
rm 29
rm 28
mkpart primary ext4 2032140288B 31268511743B name 28 userdata
name 28 userdata
mkpart primary 31268511744B 31268517375B name 29 grow
name 29 grow
print
you should see the userdata partition with the new size, and the grow partition after.
Exit from parted by typing
Code:
Code:
quit
Now reboot in fastboot mode and from pc terminal type:
Code:
Code:
fastboot format userdata
ok reboot (wait it take its time) it should be solved.

ZP980 unbrick/study of partition table

Hi to all, I hope to be posting in the right section...otherwise...punish me plz
It's a long story, so i hope that someone has time and want to put some effort to help me understand what i'm doing wrong.
By the way i work in IT field and have some knowledge about linux (let's say 5 on 10) but not so many on how android really works, but i'm confortable with custom recovery and roms, i'm still using an s4 mini (GT-I9195) with mine android 9 custom rom and i'm super happy with it.
Now that presentation are done , here is the matter.
I've found an old zp980 32GB (NOT the "plus one") that some years ago i've rooted it flashed with recovery and custom rom. all was working, but at some point i started playing with fdisk and parted and i messed up things.
Honestly i don't remember what exactly i was doing, but now the status of the phone is:
System not booting
I can enter into Recovery (custom TWRP by dezmen3 v2.4.4.0)
I can connect to adb into recovery
I cannot flash rom trough recovery due the actual system partition (589 MB)
I cannot flash the original rom trough SP flash tool due "SFT enable dram failed (4032)" error
The partitions actually are (what i can see from recovery):
System (589 MB)
Data (54MB)
Boot (6 MB)
Recovery (6MB)
Cache (4 MB)
uboot(0 MB)
nvram (5 MB)
Free space: 27412 MB
Actually, I've tried to reformat the memory using SP flah tool, but i got the same error "SFT enable dram failed (4032)", all drivers are ok, i can see COM port in deivce manager tried win 10 and even win 7.
SP tool ver. used v5 1720 more updated version tells me that the brick i'm tringo to flash in not supported anymore xD
Here a dump of fdisk -ul /dev/block/mmcblk0 from adb shell
Bash:
Device Boot Start End Blocks Id System
/dev/block/mmcblk0p1 1024 1022 2147483647+ 5 Extended
Partition 1 does not end on cylinder boundary
/dev/block/mmcblk0p2 26624 47103 10240 83 Linux
Partition 2 does not end on cylinder boundary
/dev/block/mmcblk0p3 47104 67583 10240 83 Linux
Partition 3 does not end on cylinder boundary
/dev/block/mmcblk0p4 93184 105471 6144 83 Linux
Partition 4 does not end on cylinder boundary
/dev/block/mmcblk0p5 134144 1465343 665600 83 Linux
/dev/block/mmcblk0p6 4869120 1022 2145049599+ 83 Linux
if i make a print from parted (pushed with adb) I get:
Error: Can't have a partition outside the disk!
Before i was also having an error saying that there was an extended partition into a logical one (don't ask me how I do it), but i removed it
So, now....what to to to rescue this device?
by the way honestly except for the instinct of "recover things that doesn't work" my main purpose is understand:
What I've messed on the partitions
Why sp flash tool can't reformat/flash the memory (i haven't tried to manually modify it again)

no brave person hat want to help me to brick it in a bad way?
EDIT NEW INFO
i've understtod that the problem was caused by
/dev/block/mmcblk0p1
and
/dev/block/mmcblk0p6
start and end were inverted , them were overflowing.
Now i used fdisk to remove part 1 (the extended), so i've lost also 5 and 6 (system and cache) and i have recreated them using 1 GB for each and using correct sector order.
now SD and try to flash a ....random compatible rom....see u later for info.
Cross your finger for me xD

flash failed it cant mount system and emmc.....
and now
~ # cat /etc/fstab
/cache ext4 rw
/data ext4 rw
/emmc vfat rw
/system ext4 rw
/sdcard vfat rw
/sd-ext auto rw

if someone has a zp980/c2 working can please post me the result of
cat /etc/fstab
from adb shell??
and a fdisk -ul?
